GAS-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 366,622, dated July 12,1887.

Application filed February 9, 1887. Serial No. 227,042. (No model.)

To aZZ whom it may concern:

Be it known that I, BENJAMIN F. FERTIOK,

a citizen of the United States, residing at Golumbus, in the county ofFranklin and State of Ohio, have invented certain new and usefulImprovementsin Gas-Regulators, of which the following is aspecification, reference being had therein to the accompanying drawings.

Figure 1 is a central vertical section taken on line 'x 00, Fig. 2. Fig.2 is ahorizontal sec tion on line g y, Fig. 1. Fig. 8 is a horizontalsection on line .2 :4, Fig. 1.

A is the lower part of the body.

13 is the induction pipe or tube through which gas is admitted.

O is the intermediate part of the body.

D is the upper part of the body, and E is the cap or top.

For convenience in putting the regulator together I usually prefer tomake the parts A and Gin separate pieces, which overlap and may beconveniently soldered to each other. So, also, with regard to thesections 0 D; and as the cap may fit loosely upon the section D, Iprefer to have these parts overlap such distance that they may beconveniently secured to each other by means of pins (1 d, thrust throughfrom the outside, the metal being suit-ably perforated to receive them.

a is an outlet-pipe for the discharge of such material as may bedeposited or accumulate at that point.

e is a filling-tube.

F is a transverse partition or diaphragm, below which is areceivingchamber, F.

f is an opening in partition F for the passage of gas. G is a similarpartition or diaphragm.

II is a transverse partition, extending across the body and dividing thespace between the partitions F G into two chambers, G H.

g g are a series of small tubes mounted in the partition G and openingat their lower ends into the chamber G. h h are a series of similartubes mounted in the partition G and opening at their lower endsinto'the chamber H. The upper ends of all these tubes are open.

I is a gasometer or buoy made of thin sheet metal and open at its lowerend, which is, by

preference, somewhat contracted, so as to fit closely the outer surfacesof the tubes g h,

which thereby serve as guides, as will be hereinafter explained.

J is a valve connected to the lower end of a valve-rod, J, which passesthence upward through a tube, 1, mounted in the partition G wholly atone side of the partition II. This valve-rod passes through the upperend of the gasometer I,to which it is secured, preferably, by means of anut, 3', below the top of the gas ometer, and a similar nut above thegasometcr, together with a packing-washer, l, or other contrivance,whereby leakage at this point is prevented; or the parts may be solderedtogether at this point.

K K is a spring interposed between the valve-rod J and a rod, L, whichforms practically an extension of the valve-rod. By preference I makethis extensible spring-connection between these two rods of a doublespiral spring, the convolutions of the outer one, K, being of so muchgreater diameter in horizontal section that one spring can be placedwithin the other and the two operate together without coming'in contactwith each other.

I have found that by this construction I can secure the desired tension,.with at the same time great flexibility, elasticity, and freedom ofmovement.

M is a supporting-bar, through which the rod L passes centrally, and towhich it is at tached by nuts ll, one on either side of the bar.

NN are posts rising from the cap E, and serew-th readed at their upperends, where they pass through the ends of the supporting-bar M, uponwhich the rod L is adjustably sup ported, as has been explained.

In operating my invention I propose to fill the space in the chamber Dbetween the gasometer I and the section D with glycerine or some othersuitableliquid up to, say, thepoint indicated by thedotted line 1?, orthercabout, part of the liquid of course rising up through the loweropcnend of the gasometer.

Of course the buoyancy of the gas within the gasometer will close ortend to close the valve J, which, however, can be so regulated by meansof the adjusting-nutsl l a a that the valve will under ordinarycircumstances remain some distance below the upper end of theV-shapedslot 0 in the valve-tube 0, so that gas will flow in through theinduction pipe or tube, thence through the V-shaped slot, thence throughthe opening f in the partition F, through the tubes 9 9, down throughthe tubes h h into the chamber H, and out through the eduction ordischarge tube a.

As will be readily understood, the pressure of the gas. within thegasometenw'ill tend to lift said gason eter and close or partially closethe valve,'thus reducing the size of the passageway for gas through theV-shaped slot, the position of the valve being determined with a gooddeal of accuracy by such gas-pressure, modified, of course, to someextent by the depth of the liquid within the chamber D and thegasometer, together with the tension of the springs K K, which may bedetermined with great accuracy by means of the adjustingnuts.

The filling or partial filling of the chamber D 'with liquid may beeffected by either removing the top E or by pouring through thefilling-tube 0.

Of course many modifications in details of construction may be made byany one skilled in the art of gas-regulators without departing fromthespirit of my invention, although I have shown that which I believetobe the best way now known to me of carrying out my improvement.

It is obvious that a single spiral spring or other form of spring mightbe substituted for the double spring K K, and the different sections ofthe body might be screwthreaded together to facilitate taking themapart.

While I prefer to employ the closed valvetube 0, provided with slot 0,for effecting an accurate regulation of the gas-pressure, yet I do notwish to be limited thereby, because under some circumstances andconditions the tube might be dispensed with.

I am aware of the fact that floats, broadly considered, have beenemployed in gas-,t egulators in conjunction with valves operated by thesaid floats, and that with each float there has been combined a spring;but so far as I know it has always been customary .to have the springbear loosely against the float for the mere purpose of holding thelatter down, the float being formed with air-compartments to act bybuoyancy to cause the float to tend to rise. In myconstruction thespring is so 0011- nected with the float that the latter is suspendedthereon, the adjustment being such that the position of the float can'beaccurately regulated by means of the spring or springs.

I do not herein claim any of the combinations set forth in the claimsappearing in my other application pending herewith, No. 232,923, filedMarch 30, 1887, preferring to claim herein the matter which is common toboth constructions, and in said other application the matterspecifically incident thereto.

the casing or body having within it a liquidchamber, of a float withinsaid liquid-chamber, the duct for leading gas into the interior of thefloat, a duet for leadinggas from theinterior of the float to the outletpassage, the valve-tube having a passage-way for the gas through itswall,'and the valve within the tube, connected with the float arrangedto move up and down by said-passageway, substantially asset forth.
